The body that washed up in a bag on the shore of Douglas Lake on Sunday might be that of a man named Gerald, officials said.

"He was wearing blue jeans and a 'Walking Dead' T-shirt, from the television show," Jefferson County Sheriff Jeff Coffey said Wednesday. "He had no visible tattoos. And we did find a name of Gerald from the clothing.

"That’s all that we have to go on. Just that name."

Shortly after 4:30 p.m. Sunday, a resident reported finding a suspicious bag on the lake shore as he walked along his property on Lake Ridge Drive in Dandridge. Deputies arrived and determined the bag contained human remains.

The sheriff's office, the Tennessee Bureau of Investigation and the Fourth Judicial District Attorney General's Office launched a homicide investigation.

Investigators spent Tuesday scouring the water for any evidence connected to the case. Nothing turned up, Coffey said.

The body was taken to the Knox County Regional Forensic Center for an autopsy. The cause of death has yet to be determined.

"We're hoping maybe by midweek (next week) we can get some more information from the forensic center," Coffey said.

The sheriff's office shared information about the case with law enforcement agencies in surrounding counties. As of Wednesday afternoon, no one had confirmed a match to a missing persons case, Coffey said.

Authorities ask that anyone with information about the case call the sheriff's office at 865-397-9411 or the Tennessee Bureau of Investigation at 1-800-824-3463.
